IMPROVEMENT IN LUBRICATING DEVICES.-

Specification forming part of Letters Patent No. 219,507, datedSeptember 9, 1879; application filed July 17, 1879.

The nature of my invention consists in the construction and arrangementof `a lubricator for carriage-wheels, or for any pulleys and wheelswhere the hub turns on a spindle, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure 1' is a longitudinal section of a wheelhub with my lubricatorapplied thereto. Fig. 2 is an enlarged vertical section of thelubricator.

A represents a wheel-hub, with axle-box B, of any suitable construction,secured therein. O is the oil-cup, provided with a projecting stem, a,having exterior screw -threads. In

the hub A is made a suitable recess to receive the lower end of theoilcup, the stem ct being l screwed into the axle-box B, as shown inFig. 1. Within the oilcup is placed a tube, 7;, which is screwed orotherwise fastened in the stem a, and has its upper end curved somewhatin the form of a swan-neck, as shown in Fig. 2,

the end opening toward the direction which the wheel is to .revolve in.The cup is then filled with oil, and the top D screwed on, a suitablerubber or leather washer, d, being placed under the top to make a tightjoint, and to prevent the jar of the Wheel from causing the top to comeoff.

At every revolution of the wheel the oil will flow from the cup throughthe tube to the spin, dle, while no matter at what position the wheelmay stop, the oil will remain in the cup. This lis owing to thecurvature of the upper end ot the tube b, as it is only for an instantduring each revolution of the wheel, and only when the wheel revolves,that any oil will pass into the tube, and through the same to thespindle.

The size of the tube will regulate thc iiow of the oil.

Having thus fully described my invention, what 1 claim as new, anddesire to secure by Letters Patent, is

In a lubricater for wheels and pulleys, the tube b, having its upper endcurved, as shown. in combination with the oil-cup C, having a projectingscrew-stem, a, substantially as and for the purposes herein set forth.

In testimony that I clailn the foregoing I have hereunto set my handthis 4th day of July, 1879.
